AUTOMOBILE-RADIAT R.

Application filed December 26, 1918.

; being had to the accompanying drawings,

forming a part hereof.

The present invention is directed to improvements inautomobileradiators, the special object sought being to construct aradiator provided with a removable core which may be of any standardtype and kept in stock, said core being made attachable to anddetachable from, a radiator tank section or frame permanently mounted onthe car As radiators are now generally constructed.

, the core and tank section or frame are practically integral, and whenoccasion arises ,for the driver to work on the engine the entireradiator must be taken off to make room for the operator and permitaccess to the engine, Again, the provision of a detachable core makes itcomparatively easy --to repair leaks-and make any other necessaryrepairs to either the outer frame or the core. \Vhere the core is of thecellular or tubular type the cells or tubes preferably terminate inhollow heads which may be readily coupledto or uncoupled from the tanksoft-he radiator frame or outer section,

and this without entailing any material loss ofthe water usuallyemployed as the circulating cooling medium, and which often can not wellbe spared. The advantages of the invention will be fully apparent fromthe following detailed description in connection with the accompanyingdrawings in which- L Figure 1 represents a iront elevation of the improed radiator; Fig. '2 is a side elevationthereof; Fig. 3 is a verticalmiddle. section on the line 3-3 of Fig. 1; Fig. t is an enlargedhorizontal section through-the upper head of the core on the line 4-4 oi,Fi r. 1 a art bein broken away Fig. 5 is a horizontal sectional detaiithrough the upper tank of the outer frainc on the line 5-43 oi :lf'ig.1; and Fig. 6 is a vertical. transverse sectional detail on the line 6 6of Fig.1.

.Referring to the i'lrawings, 1 represents 'an outer frantic providedwith upper and lower terminal hollow conunirtnienis or Specification ofLetters Patent.

tanks 15 and t respectively, the upper tank serving as the intake andthe lower tank as the discharge for the circulating cooling medium(water), the rear wall of the tank t being tapped by the teed or supplypipe '2 and the corresponding wall of the tank If being tapped by thedischarge pipe 3 leading from the engine as well understood in the art.The bottom wall in of the tank 6 and the upper wall w of the tank t aremade sloping, the same converging rearwardly as shown (Fig. 3) tofacilitate the mounting of. the detachable core of the radiator. Thecore-body C is herein shown as of the conventional cellular type, theopposite open terminals of the circulating cells being provided with theusual slotted plates 4, the slots s whereof terminate near the opposite.edges of the plates, e marginal imperforate portions of the platesbearing against the ledges or slwulders a formed respectively on theinner walls of the upper and lower hollow circulating heads 5 and 5terminating the core-body and coininunicating with the passage-ways orcells thereof through the slits s as well understood .in the art. Thetop and bottom walls of the core heads 5, 5', respectively are madesloping to conform to the pitch of the walls in, an, of the tanks f, t,the front walls of the said hcads having i'ornicd integrally therewiththe hollow bcnds or goose necks 6, 6, respectively, the free uppcr'orintake terminal of the bond 6 bcing inscrtible into an opening in the.l'ront wall oi the tank I, and the free lower discharge terminal of thebond (3 being inscrtible into a corresponding opcniiv of the front walloi the tank t, the inner laces of said front walls on cithcr side of theopenings receiving the tree terminals oi" the bcnds or goosonocks, beingformed with hollow bosses in for receiving the screw studs 7, the saidstuds being drivcn into the bosses with a tight iii the studs 7 arescicw-threaded, the threaded portions being freely passed throu hopenings in die side lobes or checks formed integrally with thecirculating bonds or goosenocks (5, G.

Disposed on opposite sides of the center oi: each head 5, 5, of the coreare pockets or depressions [L which receive pads or blocks 8 a shockabsorber; and being yielding, it fa- The outer ends of cilitates theinsertion'of the core body and its heads into the outer frame 1. \Vhenthe parts are assembled, suitable blind nuts 12 passed over the outerthreaded ends of the studs 7 clamp the core to the outer frame, it beingunderstood that the core herein includes the core-body C and its heads5, 5, and as shown constitutes the removable or detachable unit of theradiator. The outer faces of the shock absorbers 8 (four being shown inthe present example, though I am not to'be restricted to any specialnumber) engage the sloping walls w, w, of the tanks 25, t, of theouterframe and take up any shocks incident to the travel of the vehicle.Between the lobes d and the outer faces of the tanks t, t, arepreferably interposed suitable packing strips or gaskets 9 to preventleakage, the gaskets being of course formed with openings registeringwith the bores of the bends 6, 6, (Fig. '3).

\Vhenever it becomes necessary to detacl the core for any purpose, allthat the driver need do is to unscrew the nuts a (four of them) when theentire unit C, 5, 5-, including the pads 8, S, and goosenecks 6, 6,slips off the studs 7 (see dotted position in Fig. 3) the open frame 1affording access to the working parts of the engine. To restore'thecore, the same is reinserted into the'frame, the parts so fitting thatwhile the core is being inserted, the openings in the lobes (Z willregister or come opposite the' studs 7, the latter passing freelythrough the openings, after which the nuts n are placed back on thestuds clamping the parts together and the radiator is again ready forservice. To prevent loss of any material quantity of water as the coreis being detached, the bottom hole of the frame or that formed in thetank t to receive'the free end of the bend 6' may be plugged up with acork or block of wood or anything handy. It is of course rare that theloss of the water can cause serious inconvenience, water being usuallyobtainable on the road. In the present embodiment of my invention theledge r by which the forward end of the hood H is supported is formed onthe frame 1. In the present embodiment of my invention I provide pocketsor depressions h for preventing displacement of the pads or shockabsorbers 8 but obviously I am not to be restricted to this specificconstruction. So too, any equivalents of the construction here shown forestablishing circulation between the core and the frame tanks arecontemplated by the present invention. Features shown but 1.. In aradiator, an outer frame provided 1 with water circulating compartmentsor.-

tanks, a detachable core inserted in and extendlng the width of theframe, water c1rculatlng connect1ons between the coreand not alluded toare well known in the art and compartments, and suitable shock absorbingdevices between the core and frame.

2. In a radiator, an outer frame provided with top and bottom tanks,acore comprising a body terminating in top and bottom hollow headsextending substantially the width of the frame and insertible into saidframe, the bottom and top walls of the top and bottom tanks respectivelybeing made sloping and converging rearwardly, and the correspondingwalls of the heads of the core being pitched to conform to the slopingwalls of the tanks, means for establishing circulation between the frametanks and core'heads through the front walls of the tanks and heads rspectively, pockets disposed on the sloping 'alls of the core heads,suitable shock absorbing elements mounted in said pockets and engagingthe sloping walls of the tanks aforesaid, inlet means for thecirculating cooling medium formed in the rear Wall of the top tank, andoutlet means in the corresponding wall of the bottom tank. I

3. In a radiator, an outer frame provided with top and bottom tanks, thebottom and top walls respectively of which slope and convergerearwardly, a core compr' ing a body terminating in top and bottomhollow heads insertible in said frame, the heads having sloping andconverging walls to conform to and engage thecorresponding-slopaforesaid, and means for establishingcirculationbetween the frame tanks and core heads through the front walls of thetanks and heads respectively.

In testimony whereof Iaffix my signature in presence of two witnesses.
